1. Technical Field
The present disclosure relates to electronic devices, more particularly, to a paper inputting apparatus.
2. Description of Related Art
In general, an image forming device, such as a printer, a scanner, or a copier, includes a paper inputting unit, which receives sheets of paper and sequentially feeds the sheets of paper. The paper inputting unit may include a stop plate including a front part and a back part. The front part is attached to the back part by or with rubber damping element. A vibrating means is attached to the front part and the back part of the stop plate. However, the rubber damping element may become worn and loose, and take-ups of the sheets of paper may become unreliable. Therefore, there is room in the art for improvement.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The release soft roller shaft 10 comprises a swing arm 11 located on a free end of the release soft roller shaft 10. In one embodiment, the swing arm 11 is integrated with the release soft roller shaft 10. Two connecting members 50 are used to connect the release soft roller shaft 10 to the first soft roller shaft 20. In one embodiment, a first end of each of the two connecting members 50 is attached to the first soft roller shaft 20, and a second end of each of the two connecting members 50 is rotatably attached to the release soft roller shaft 10, so the first soft roller shaft 20 and the two connecting members 50 extend radially from the release soft roller shaft 10. Two elastic members 60 made of rectangular strips of resilient material having low-friction surfaces, are attached to the release soft roller shaft 10 by such means as, for example, jointing, belting or riveting.
A plurality of idler sleeves 21 are attached to the first soft roller shaft 20, and a plurality of soft rollers 31 are attached to the second soft roller shaft 30. In one embodiment, each of the plurality of idler sleeves 21 and each of the plurality of soft rollers 31 is made of latex or other soft, high-friction, material.
The driving device 40 comprises a driving member 41, a cam 43, and a transporting pole 42 connected to the driving member 41 and the cam 43. The driving member 41 may be a motor, for example. The cam 43 abuts the swing arm 11, and comprises a first part with a first radius and a second part with a second radius. The first radius is greater than the second radius.
The driving device 40 is capable of rotating the release soft roller shaft 10 and the first soft roller shaft 20 relative to the second soft roller shaft 30 between a first position as shown in
Referring to
When the sheet of paper 70 is slid out of the paper inputting apparatus, the driving member 41 rotates the cam 43 from the second position to the first position. The first part abuts the swing arm 11, and each idler sleeve 21 abuts each soft roller 31. The first soft roller shaft 10 and the two connecting members 50 are rotated to the first position, and the two elastic members 60 abut the first soft roller shaft 20 to await a next sheet of paper.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
